Easy Pate Sucree

Pulse flour, sugar, and salt in a food processor to combine. Add butter; process until mixture resembles coarse meal, about 10 seconds. Add yolk; pulse. With machine running, add ice water in a slow, steady stream through feed tube; process until dough just holds together (no longer than 30 seconds). Shape into a disk. Wrap in plastic, and refrigerate at least 1 hour (up to 2 days)
